Part of your driving test will involve a show me, tell me set of questions before you leave the test centre. These questions are designed to test your knowledge of car maintenance and safety. Your driving examiner will ask you two show me tell me questions before your practical driving test begins. These questions can include questions about oil level, power assisted steering, engine coolant, parking brake, horn and other parts of the car. It is important to know the answers to these questions and you can find all the information on Show me, Tell me on the driving-test-success website.
